Steroidogenesis is essential for the production of sex steroids, and therefore also the sexual maturation process. The rate-limiting step in steroidogenesis is the movement of cholesterol from the outer to the inner ...

Background
Although arctic lakes have responded sensitively to 20th-century climate change, it remains uncertain how these ecological transformations compare with alpine and montane-boreal counterparts over the same ...

The waters surrounding the South Shetland Islands, Antarctica, comprise a
coastal/oceanic ecosystem that is iron-fertilized naturally from shelf sources of
Weddell Sea origin. My thesis incorporates data from an 18-year ...

Pollen records from large lakes have been used for quantitative palaeoclimate reconstruction, but the influences that lake size (as a result of species-specific variations in pollen dispersal patterns that smaller pollen ...

The thesis provides a qualitative geographical/socio-anthropological case study and ethnographic description of rainwater harvesting cisterns and their role in local water management. The analysed data is presented in a ...

Sandy beaches with accompanying immature dunes as well as mature sand dunes are regarded a rare biotope in Norway. The localities of this survey are situated at the south west coast of Karmøy. As a former resident of the ...

Background In host-parasite evolutionary arms races, parasites are generally expected to adapt more rapidly, due to their large population sizes and short generation times. There exist systems, though, where parasites ...

Six 3D models of the digestive system during ontogeny were reconstructed from histological sections of Atlantic cod larvae. The 3D models clearly visualize the following features: folding of the gut rotation; subdivision ...

The time taken for forested tropical ecosystems to re-establish post-disturbance is of widespread interest. Yet to date there has been no comparative study across tropical biomes to determine rates of forest re-growth, and ...

The topic of this thesis is recruitment processes in Greenland Halibut (Reinhardtius
hippoglossoides) in West Greenland waters. The focal point is Greenland halibut’s
early life history from oocytes in the female ovary ...

A redescription of Protoopalina pingi Nie, 1935 is presented in this paper to complete Nie’s description at both light and scanning electron microscope levels. These organisms were collected from the recta of the frogs ...

With regard to predicted oceanic warming, we studied the effects of heat stress on the redox system during embryonic development of Atlantic cod (Gadus morhua), with emphasis on the glutathione balance, activities of key ...

This study aims to evaluate the direct effects of anthropogenic deforestation on simulated climate at two contrasting periods in the Holocene, ~6 and ~0.2 k BP in Europe. We apply We apply the Rossby Centre regional climate ...

The Hardangerfjord is one of the largest salmon-farming areas in Norway, with an annual production of approximately 70,000 metric tonnes. The regional impact of fin-fish farming in a fjord environment was studied during ...

High water temperature combined with low dissolved oxygen (LO or hypoxia) is one of the most challenging environmental conditions farmed fish experience. The oxygen requirement of fish increases in parallel to this, which ...

from its feeding grounds in the Barents Sea to various spawning banks along the Norwegian coast.
Prior to the 1990s these banks were located on a wide latitudinal range from Finnmark (~71º N) to
Møre (~63º N), or even ...

Background: In many environmental genomics applications a homologous region of DNA from a diverse sample
is first amplified by PCR and then sequenced. The next generation sequencing technology, 454 pyrosequencing,
has ...
